A system architecture integrates spreadsheet fields and functionality into text. In one implementation, a free floating field is presented in line with text in a document. The free floating field is configured to present content derived from a source. Upon modification of the source, the content in the free floating field is automatically updated to reflect changes to the source. In a particular implementation, where the source is a spreadsheet, modifications made to the spreadsheet are then reflected in updates in the free floating fields of the text.
